摘要
飞机起落架结构设计在满足一定结构刚度的前提下,应尽可能地轻量化。采用ABAQUS/CAE中的优化模块对起落架的扭力臂进行拓扑优化,基于条件算法建立优化任务,最终优化后的拓扑结构体积下降49.15%,最大应力下降4.09%,实现了轻量化的设计需求,为起落架的优化分析提供参考。
The design of aircraft landing gear structure will be as lightweight as possible on the premise of meeting certain structural stiffness.The optimization module in ABAQUS/CAE is used to optimize the topology of the torque arm of the landing gear,and the optimization task is established based on the conditional algorithm.Finally,the volume of the optimized topology is reduced by 49.15%and the maximum stress is reduced by 4.09%,which realizes the lightweight design requirements,and provides reference and guidance for the optimization analysis of the landing gear.
